Why Choose the GE0250DT4?
Engineered for photovoltaic isolation, the Lovato GE0250DT4 is a four‑pole DC switch disconnector delivering reliable manual control at 250 A Ith. With Ui 1000 V and Uimp 8 kV, it safeguards circuits during installation, maintenance and emergency shut‑downs. The direct operating, door‑coupling design supports safe, positive isolation, while screw‑on plate mounting streamlines panel integration. Built to IEC/EN 60947‑1 and 60947‑3, it provides trusted performance in demanding PV arrays.
Rated IP20 at the front and Pollution degree 3, this GE series device operates from -25 to 55 °C and up to 3000 m altitude, with 20,000 mechanical cycles for long service life. Storage from -40 to 70 °C aids logistics and resilience. Designed for screw‑on plate installation, it enables dependable DC isolation in photovoltaic panels and enclosures, supporting safe maintenance and system commissioning.
